Serial Transceiver APC220-43

[kawthar]

Hello,

I just wanna ask if anyone had used this APC220-43 transceiver module before with serial VISA?

Because it didn't work at all with just the example of Basic serial write & read. I'm afraid I might not be able to proceed with my project if it really is not compatible with LabVIEW. 

Thanks in advance for replying!

Any luck communicating with the APC220?  I just got one and am having problems comunicating with it also.

hello

I managed to communicate with the APC module. What problem are you facing exactly?

[bears]

I am unable to get it comunicate at all using VISA.  I am able to comunicate with it now using .NET modified from here:

https://decibel.ni.com/content/docs/DOC-8092

with a baud rate at 4800.  However, it seems to be not reliable at all with characters outside the keyboard character range of 0x20 to 0x7E.

hello,

have you modify the RTS mode inside the VISA configure serial port?

Thanks for the link, I'll take a look at that right away.

I haven't done anything to the RTS within VISA.  I am able now to get it fully working using .NET with the write BYTES method instead of the write CHAR method as shown in the example linked previously.

Good afternoon! Prompt please as you managed to connect APC220-43? I badly know English language. I have established the driver on APC220-43 in LAb this arrangement was displayed as COM port but to be connected to it I have it does not go right. How properly to configure it? If it is possible an example. Thanks for the answerет

I was unable to get the APC220-43 to work properly using the LabVIEW VISA tools.  Using the .NET method works well using the write byte method as shown

Many thanks, I shall try your method

After finding the actual code I used I noticed I added a few more things in the configuration.  I'm not sure if all the changes were necessary but I do remember that the handshaking needs to be set to NONE instead of RequestToSend as set as default in the above example.
